Hexahydro Phthalic Anhydride

One of the advantages of HHPA is its low toxicity and low volatility, which makes it a safer alternative to other phthalic anhydride derivatives. It also has a low melting point, which makes it easier to handle and process in industrial applications. However, it has a relatively high viscosity, which may require heating to facilitate mixing and processing.

FAQ 

1. What is Hexahydro Phthalic Anhydride (HHPA)?

Ans - HHPA is an organic compound used to produce polyester fibers, plastics, paints, and resins. It is a colourless, odourless liquid with a boiling point of 285 Deg C.
